However, statements from SpaceX suggested the problem was with ground support systems, not the rocket itself.

After launch, the mission achieved a quick succession of feats: a first stage engine cutoff followed by a stage separation, and then a second stage burn and fairing release. Moments later, the second stage cut its burn.

By the end of the year, Musk aims to fly two missions with the same rocket in the span of 24 hours. He likened the rocket's reusability to an airplane -- capable of landing, refueling and flying again on a quick turnaround.

"We expect it to be a mainstay of SpaceX's business," Musk said, "and to complete something of the order of 300 flights before retirement."
